I finally did the KOOKS long tube setup.
It really did wake the car up quite a bit, as shown in the attached dyno sheet.
Oops, no can attach dyno sheet - RWHP went from 402.76 to 424.49; tq went from 353.3 to 372.05
Most significantly, A/F went richer on the KOOKS, from 12.28 stock to 12.63 on KOOKS. Looks like the FOMOCO closed loop ecu actually works...
This is on test pipes w/o cats.
I was curious as to what others with KOOKS will do when it comes time to update their Track Key.
According to my dealer they cannot update track key without the stock exhaust, since the program must run a diagnostic (which will fail w/o cats) before the upload is accepted by the ecu.
- Anyone run into this?
- Anyone tried putting their ecu into a stock 302 for update purposes or purchased a second ecu as a mule?
- Anyone found a good tune for the 302; i.e. reliable for track duty?
I personally would not in any way consider reinstalling the stock exhaust setup for dealer purposes since the KOOKS job is indeed a bear.
Thank in advance for any replies.
